  • Comparative Study of NZ Pine & Selected SE Asian Species
    (FRONT COVER) A COMPARATIVE STUDY OF NEW ZEALAND PINE AND SELECTED SOUTH EAST ASIAN SPECIES (INSIDE FRONT COVER) NEW ZEALAND PINE - A RENEWABLE RESOURCE NZ pine (Pinus radiata D. Don) was introduced to New Zealand (NZ) from the USA about 150 years ago and has gained a dominant position in the New Zealand forest industry - gradually replacing timber from natural forests and establishing a reputation in international trade. The current log production from New Zealand forests (1998) is 17 million m3, of which a very significant proportion (40%) is exported as wood products of some kind. Estimates of future production indicate that by the year 2015 the total forest harvest could be about 35 million m3. NZ pine is therefore likely to be a major source of wood for Asian wood manufacturers. This brochure has been produced to give prospective wood users an appreciation of the most important woodworking characteristics for high value uses. Sponsored by: Wood New Zealand Ltd. Funded by: New Zealand Ministry of Foreign Affairs and Trade Written by: New Zealand Forest Research Institute Ltd. (Front page - First sheet)) NEW ZEALAND PINE - A VERSATILE TIMBER NZ pine (Pinus radiata D.Don) from New Zealand is one of the world’s most versatile softwoods - an ideal material for a wide range of commercial applications. Not only is the supply from sustainable plantations increasing, but the status of the lumber as a high quality resource has been endorsed by a recent comparison with six selected timber species from South East Asia. These species were chosen because they have similar end uses to NZ pine.

  • Biosynthesis of Indigo Using Recombinant E. Coli: Development of a Biological System for the Cost­ Effective Production of a Large Volume Chemical
    BIOSYNTHESIS OF INDIGO USING RECOMBINANT E. COLI: DEVELOPMENT OF A BIOLOGICAL SYSTEM FOR THE COST­ EFFECTIVE PRODUCTION OF A LARGE VOLUME CHEMICAL Alan Berry, Ph.D., Senior Scientist; Scott Battist, B.S., Ch.E., Development Engineer; Gopal Chotani, Ph.D., Ch.E., Senior Staff Scientist; Tim Dodge, M.S., Ch.E., Senior Scientist; Steve Peck, B.S., Ch.E., Development Engineer; Scott Power, Ph.D., Vice­ President and Research Fellow; and Walter Weyler, Ph.D., Senior Scientist Genencor International. Rochester, NY. 14618-3916. Abstract Cost-effective production of any large-volume chemical by fermentation requires extensive manipulation ofboth the production organism and the fermentation and recovery processes. We have developed a recombinant E. coli system for the production of tryptophan and several other products derived from the aromatic amino acid pathway. By linking our technology for low-cost production oftryptophan from glucose with the enzyme naphthalene dioxygenase (NOO), we have achieved an overall process for the production ofindigo dye from glucose. To successfully join these two technologies, both the tryptophan pathway and NOD were extensively modified via genetic engineering. In addition, systems were developed to remove deleterious by-products generated during the chemical oxidations leading to indigo formation. Low-cost fermentation processes were developed that utilized minimal-salts media containing glucose as the sole carbon source. Finally, economical recovery processes were used that preserved the environmental friendliness ofthe biosynthetic route to indigo. 1121 Introduction Two major problems facing the U.S. chemical industry are dependence on foreign petroleum and mounting environmental concerns and regulations (for review, see reference [1]). This has led to consideration ofbiosynthetic routes for production of aromatic compounds.

They required preliminary data on pre- eminent commodities in the districts/cities, descriptions of the land types suitability and factors that are expected to affect investment realization. Each city and district has different land suitability data. The five districts studied Generally have two types of soil, namely, red yellow podozolic soil and peat soil (organosol). The city of Jambi has more reGional advantaGes compared to other districts because it is supported by a strateGic location, has appeals to investors due to the elevated location and the distribution of the inlands/districts. Muaro Jambi regency as the main zone city should be able to anticipate the city faster development for example by developing palm oil or rubber derivation industry with red yellow podzolic condition. The similar case applies to the upstream of West TanjunG JabunG which needs to be prioritized and investment promotion breakthrough. Whereas, the downstream of West Tanjung Jabung is expected to capture investment opportunities in fishery or aquatic sub-sector.
